: Oops! I phoned the company and found out the roller is made of rubber, and
: they don't make a smooth metal roller.

: Do you have any other ideas?

: Thanks.

Hi Dave,
Why not make one? A wide bearing on a shaft or bolt through the end of a handle should be easy to make.
If you're heat activating the glue, warm the bearing so it doesn't soak up the heat too quickly. A pan of hot water will do.
Oh yeah, de-grease the bearing, it doesn't need the lube and neither does the pvc/glue.

If you need a wider roller, you could use a skateboard wheel. The material is quite hard but can be trimmed so the contact surface is level rather than slightly curved.

Hope this helps,
